Bastion game hangs with 17.3.1 mesa on Skylake. The newest 19.0.0 mesa works
well so I've bisected this. It was fixed by commit:

468a2b6525f3b1e950d8b14138ccf62227aab73a is the first fixed commit

        i965/miptree: Add an aux_disabled parameter to render_aux_usage

        Only one of the callers of intel_miptree_render_aux_usage actually took
        brw->draw_aux_buffer_disabled into account.  This was causing us to
        ignore draw_aux_buffer_disabled for the intel_miptree_prepare_render.
        This isn't a problem because the draw_aux_buffer_disabled entry was set
        during texture preparation and we already did the resolve at that time.
        However, this also meant that the aux_usage we were passing to
        brw_cache_flush_for_render and brw_render_cache_add_bo was wrong so our
        automatic cache flushing around aux_usage changes wasn't happening.
        This was causing GPU hangs in Oxenfree.
